In most hygienic production environments, hoses are the arteries of the process line. Among the many hose styles available, rubber sanitary hoses remain a popular work‑horse option thanks to their combination of flexibility, robust mechanical strength, and cost‑effectiveness.
What Is a Rubber Sanitary Hose?
A rubber sanitary hose is a food‑grade or pharmaceutical‑grade hose constructed with an EPDM, nitrile or other elastomeric inner tube, reinforced with textile and/or steel wire, and finished with a smooth, easy‑to‑clean cover.
Industries That Rely on Rubber Hoses
- Food and Beverage: Bulk transfer of juices, sauces, syrups, dairy products and more. One of our most popular hoses for food and beverage processing is the Novaflex FDA Food Transfer Hose Assembly (FTH).
- Breweries or Wineries: Hot‑wort transfer, must handling, cellar racking and bottling operations. Our brewing customers prefer the Brewery Transfer Hose (BTH).
- Pharmaceutical: Non‑critical media transfer, buffer preparation and waste handling.
- Personal‑Care & Cosmetics: Viscous creams, gels and lotions that need gentle handling.
- Industrial CIP or Wash‑down: Hot‑water or caustic cleaning lines that demand abrasion resistance.
How a Sanitary Facility Uses Rubber Hose
Inside the plant, rubber hoses excel wherever moderate temperatures, frequent movement or vibration are present:
- Tank Unloading & Loading: Flexible connections between storage tanks and fixed piping.
- Suction & Discharge Lines: Pump inlets/outlets handling viscous or particulate‑laden fluids.
- Filling & Packaging: Quick hose change‑overs reduce downtime between product runs.
- CIP Chemical Transfer: Compatible EPDM tubes carry alkaline or acid detergents safely.
Key Benefits of Rubber Hoses
- Exceptional Flexibility: Tight bend radii fit crowded production floors better than rigid piping.
- Abrasion & Impact Resistance: Thick covers protect the reinforcement when dragged across floors.
- Thermal Shock Tolerance: Withstands repeated hot‑water wash cycles without cracking.
- Vibration Damping: Absorbs pump pulsations, reducing stress on welded pipework.
- Cost‑Effective: Lower material cost than PTFE or stainless‑braided alternatives, yet durable.
Potential Drawbacks & Considerations
- Clean In Place (CIP) Complexity: A textured rubber core can trap residues if not flushed thoroughly.
- Lower Chemical & Temperature Limits: Not suitable for aggressive solvents or sustained temperatures above roughly 225 °F / 107 °C.
- Permeation & Odor Transfer: Extended contact with aromatic products may require more frequent hose replacement.
- Weight: Heavier than silicone or PTFE hoses, which may influence ergonomic handling.
Selecting the Right Rubber Hose
When purchasing a hose, verify:
- Media Compatibility: Match elastomer (EPDM, nitrile, etc.) to the fluid’s pH, fat content and solvent load.
- Temperature & Pressure Ratings: Review the worst‑case CIP and production conditions.
- Bend Radius & Length: Ensure adequate flexibility without excessive torsion.
- Cover Type: Smooth for easy wipe‑downs, corrugated for extra flexibility or crush resistance.
